Updated: 2026-09-16

Overview

C.I. Pigment Yellow 12 is a synthetic organic pigment belonging to the diarylide yellow class. It is widely recognized for its vibrant yellow color and cost-effectiveness, making it a popular choice in industrial applications. The pigment is chemically stable and offers excellent performance in terms of lightfastness and heat resistance. First introduced in the mid-20th century, Pigment Yellow 12 has become a staple in the pigment industry, particularly for printing inks and plastics. Its versatility and affordability have cemented its position as a go-to option for manufacturers seeking reliable coloration solutions.

Physical and Chemical Properties

Pigment Yellow 12 appears as a fine yellow powder with a molecular weight of 629.49 g/mol. It is insoluble in water but can dissolve in certain organic solvents, which makes it suitable for a variety of formulations. The pigment exhibits a bright yellow hue with good tinting strength and opacity. Key chemical properties include its stability under normal processing conditions and resistance to fading when exposed to light. Its density is approximately 1.35 g/cm³, and it does not have a defined melting point, as it decomposes before melting. These characteristics make it ideal for high-temperature applications such as plastics molding.

Main Applications

The primary use of Pigment Yellow 12 is in the production of printing inks, especially for packaging and publication printing. Its bright color and excellent lightfastness ensure that printed materials retain their visual appeal over time. The pigment is also widely used in plastics, where it provides consistent coloration for products like toys, containers, and automotive parts. In addition to inks and plastics, Pigment Yellow 12 is employed in coatings for metals and textiles. Its ability to withstand processing temperatures and environmental exposure makes it a reliable choice for industrial coatings and dyed fabrics. The pigment's versatility extends to artistic applications, where it is used in acrylic paints and other art supplies.

Safety and Storage

While Pigment Yellow 12 is generally considered safe for industrial use, proper handling precautions are necessary to minimize risks. Workers should avoid inhalation of dust and direct skin contact by using personal protective equipment (PPE) such as gloves and masks. The pigment should be stored in a cool, dry place, away from direct sunlight and moisture to prevent degradation. Regulatory compliance varies by region, but Pigment Yellow 12 is not classified as hazardous under most standards. However, manufacturers should always refer to local regulations and safety data sheets (SDS) for specific guidance. Proper disposal methods should be followed to prevent environmental contamination.

B2B Procurement Guide

When sourcing Pigment Yellow 12, B2B buyers should prioritize suppliers with a proven track record of quality and consistency. Key factors to consider include the pigment's purity, particle size distribution, and compatibility with intended applications. Buyers should request samples and conduct performance tests before placing large orders. Price negotiations should take into account order volume, with bulk purchases typically offering cost savings. It is also advisable to establish long-term relationships with suppliers to ensure stable pricing and reliable supply chains. Buyers should verify the CAS number (6358-85-6) to avoid counterfeit or substandard products.
